Assuming you actually change the jumpers to give you 1Meg of Chip RAM as well, the FastMemFirst program becomes obselete. >I have a 2000 with an A2620 (with 2Meg) + the old Commodore 2meg memory >board. How will I make sure that the programs first use 32bit memory, then >normal FAST and last CHIP ram? The A2620 design assures that, by being the first autoconfig unit in the configuration chain. The OS always orders memory of the same kind in the order is was found in the configuration chain. >Tommy Petersson -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy ONLY 230 MILES TO GO

There's no need for FastMemFirst if yoou have no $C00000 memory. The
32 bit memory starting at $200000 is used first without any extra massaging
on your part. The only things I know of that allocate from the top down are
recoverable ram disks and the like...
I'm using a WordSync in my machine here at work with the 2620 and I
am having no problems. I used to use the Wordsync with my 2630 at home...
What kinds of troubles are you having?

I finally got into contact with Supra US, and they said it was a problem with an old version of their aotoboot ROM and a PAL. They should send new chips, I hope they do. Tommy Petersson
